qcacld-3.0: Add SAP channel auto selection DCS callbacks with AFC

Add channel tx max power factor to existing ACS channel weight logic,
so if AFC available can automatically select Standard Power channel
which has higher 6 GHz tx power and better performance.

Add SAP best channel selection callback when AFC triggered DCS,
DCS module will invoke this callback and dynamic switch to best
channel/bandwidth if possible.
